Funding is principally in the form of Recurrent and Capital (Public Sector Investment Programme-PSIP) Budgets from the Ministry of Finance via the Ministry of Home Affairs.

The organisation generates its own resources principally from entrance fees to sites and museums. Further resources are generated through the sale of publications, consultancy fees, filming, accommodation and auditorium hire and investments. Recognition must also be given to donors who fund special projects, which make a significant contribution to the achievement of the objectives of the organisation.

These donors include the Government of France, MS Zimbabwe, The Beit Trust, New Zealand Aid and the Government of Germany. NMMZ welcomes financial and technical support from any other interested parties.
